    I downloaded ffmpeg and used it with some existing mpegs that I had and it worked flawlessly when converting them to .flv files.

    However, after a day-long search, I cannot find a cut-and-dry answer to this issue with iMovie files:

    I import video into iMovie, arrange my clips and all of that, then export the movie as a .mov (or any other format for that matter).

    I then add that file to ffmpeg, and select .flv as my final output.

    I click "Encode" and it is done encoding in less than a second.

    Of course, when I then play back the zero-kb .flv file it created, there is nothing.

    Please help as it may be a setting that I am overlooking.

    Thanks in advance for any assistance you can give me.
    Blessings, JD

    In the ffmpegX Process window, press the blue "i" () to access the log. Post that here, as it should list the reason for not encoding to FLV.

    Uncheck the "Invert mapping" checkbox. It is not needed for this conversion.

    Is your version of ffmpegX the latest? Does it read "0.0.9x r2" in the About box?

    Just curious:

    What happens if you select the iMovie Project in the finder,
    go to "show Package contents", select the iDVD folder,
    and then select that movie ref file therein
    ( which will contain all your cuts and edits)
    and drag and drop that into ffmpegx, and then process that
    as .flv?
    (of course as Case said, leaving the invert mapping
    option unchecked)
    Does this work? Do you get a playable file?

    Audio listed before video; you should check the Invert mapping checkbox in the Audio tab..

    I got it working by converting a .dv file to flv. To get a .dv file from iMovie, select File -> Export -> Compress movie for "Full Quality".

    Only problem I'm having now is that sometimes I add images to the .dv file from QuickTime, and when that is done the file becomes a .mov file instead of a .dv file, so the above solution won't work in that case.

    Thanks for the input but this program really seems klugy. Glad I didn't buy it but only tried the demo.
